The roots of quantum incompatibility go back to Heisenberg’s uncertainty principle and Bohr’s notion of complementarity. Incompatibility is traditionally thought of as a property of a collection of measurements, but the concept can be easily generalized to quantum channels. The quantification of quantum incompatibility advances our understanding of this fundamental quantum feature. In this talk, I will introduce our proposed methods that employ the Jordan product to quantify incompatibility in both measurements and channels.
